Zemlyanoy A. Ecological adaptations of micromammals in the conditions of tehniogenic contamination of Pridneprovya steppe biogeocenosis

The object of Rodentia and Insectivora, which are representativi unite in the ecological group "small mammals". A purpose - determination of character of ecological adaptation of small mammals, as important elements of biogeocenosis, in the conditions of tehnogenic press Methods - bioecological, morphophysiological, biochemical, physical and chemical. The influencing of tehnogenic contamination on the species composition, biodiversity indexes, changing is of size characteristics and morphophysiological indicators of micromammals. The corelelation between microelements contain anol species belonging is exposed. Coefficient of elements accumulation decrease in animals in contaminate ecosystems. Biochemical indexes changing in tehnogenic polluted areas are observed. The population's indexes change by spatial structure modification and by increasing of elder animal groups quantity in contaminated ecosystems. Besides, the tendency of females prevailing and indexes reproduction in the conditions of transformation is revealed. Coefficient of microelements output in animals from the plots with different contaminative degree is calculated. Coefficient of accumulation microelements in the following chainlet soil - plants - animals descries in polluted ecosystem. A table of the degree contamination determination ecosystem on ecological, populations and morphophisiological indexes is made. Application spheres are bioindication and traning courses.
